Sweet!  Is it the yellow enclosure or the blue enclosure?

My ADM-3A is the yellow enclosure which seems to be less common and
does *not* have the graphics option.  What's in the graphics option
anyway?  Block character graphics?  I hadn't heard of this.

Some sites talk about removing the face plate and cleaning it and
reattaching it, but I've only seen sites talk about this as a
possibility, not any stories from anyone who's actually done it.  I
think replacing the CRT would be preferable.

My ADM-3A also does not power up; I suspect the power supply circuit
but haven't diagnosed it any further than that.

Perhaps a steam cleaner would make quicker work of dissolving the
dried syrup so it can be sponged off?
